Police were reportedly called to Reinhardt's home in the Hollywood Hills when neighbors complained about noise.
E! reports police were called back again when pricey cars parked in the neighborhood were egged.
Initial reports were that party guests had done the deed, but Hilton says it's not true.
"We had nothing to do with this. My blue Bentley was egged and I even filed a victim's report," Hilton tells E! in an online exclusive.
